DESIGNED FOR ATHLETESWHO NEED TO SPEAK

Quarterbacks, Linebackers, Hockey and Basketball players all need to communicate with their teammates. The Nano 3D offers all the protection of a Shock Doctor mouthguard in an unltra slim design so you can speak easy. This extremely lightweight piece of equipment forms to fit your exact bite, helping to eliminate bulk and improve airflow. Our enhanced protective shock frame now offers a thinner wall, designed to absorb and disperse impact away from the point of contact.

One third smaller than traditional mouthguards, the Nano 3D is the smallest, lightest mouthguard for elite athletes who need to speak freely without sacrificing protection.

I really like the fit and feel of this mouth piece - but the adult / large size does not go all the way to my back teeth. I don't know if this is by design, but its different than any other mouth piece I've used. I'm not a complete caveman, I don't have a giant head... I still wear it, and like it - its just not what I'm used to. Not sure if they offer an XL or not.

I heard good things about the brand (SD) at the gym and bought this mouthguard to see if it was better than my old one that i payed 4 bucks for,The sd mouth guard was hard (impossible for me) to mold even tho i followed the instructions from top to bottom after numerous attempts i gave up..
